低温胁迫对水稻生长与产量品质的影响及应对措施

Effects of Low Temperature Stress on Growth,Yield and Quality of Rice and Countermeasures

在水稻生长发育过程中,低温胁迫是影响水稻生理生化进程并降低产量的主要非生物胁迫之一。为了提高水稻在低温胁迫条件下的抗逆性,通过归纳低温胁迫对水稻生长发育、产量和品质的研究现状,总结低温胁迫对水稻生理指标、产量指标及品质的影响,分析抵御低温胁迫的应对措施和有效方法。指出目前应对低温存在的问题并提出解决方案,以期降低低温胁迫对水稻生长造成的伤害。

Low temperature stress is one of the main abiotic stresses that affect the physical and chemical process and reduce the yield of rice in the process of rice growth and development.In order to improve the stress resistance of rice under low temperature stress,the research status of low temperature stress on rice growth,development,yield and quality was summarized,and the effects of low temperature stress on rice physiological index,yield index and quality were summarized,the countermeasures and effective methods to resist low temperature stress were analyzed.The problems existing in dealing with low temperature were pointed out,and solutions were put forward in order to reduce the damage caused by low temperature stress to rice production.
